Volume totalled 783 million shares worth 941 million Singapore dollars (570 million US), from 1.15 billion shares valued at 947 million dollars on Friday.
"It's a quiet market compared to last Friday, without any new leads to prop up the market. Investors are probably disappointed with the performance of select blue chips, with earnings results from DBS failing to boost the market," a dealer at a local brokerage said.
DBS declined 40 Singapore cents to 15.60 Singapore dollars after its fourth-quarter results on Friday showed that net interest margin fell even as total 2004 net profit hit a record high, dealers said.
Among other banking stocks, United Overseas Bank was steady at 14.30 and Oversea-Chinese Banking Corp remained unchanged at 13.80.
Other blue chips closed mixed, with Singapore Press Holdings rising two cents to 4.56, Singapore Telecommunications gaining two cents to 2.63, while Singapore Airlines closed flat at 12.40 and ST Engineering dropped two cents to 2.45.
Technology counters also closed mixed, with Chartered Semiconductor gaining a cent to 1.20 and STATS ChipPAC up three cents at 1.09, while Creative Technology was down 70 cents at 20.70, Venture Corp lost 60 cents to 16.00 and UTAC declined by 0.5 cents to 69.5 cents.
ACCS was the most briskly traded stock, ending the session up five cents at 72 cents.
